We don't have a rocker, but we have a chair/ottoman. The chair does glide/rock though, so it was a big help. The chair will most likely just stay in DD's rooms as she grows up because it really doesn't look "babyish". We got it at Pottery Barn Kids. They have a huge selection of chairs, and more patterns than you'll know what to do with! GL!
I do not have a glider yet but will be purchasing one soon. I've heard of people getting a great deal on the ones from Wal-Mart and they are cheaper there so I'll probably be buying one from there soon.
Got mine from Babys R us when they had an extra 25% off sale. We went with Dutailier (sp?) because there was one that was narrower and a little more modern. Haven't gotten to use it yet though!

We love it. Some people said that it was too small but my husband is a big guy and he can fit comfortably.
